Key Features
Synchronous Tilt Mechanism: Backrest and seat recline at a 2:1 ratio, maintaining proper lower back support while keeping feet flat on the floor.
Independent Seat Depth Adjustment (Slider): Allows users with different heights to adjust the seat pan forward or backward by 50 mm, reducing pressure behind the knees.
3D Adjustable Armrests: Adjusts vertically (70 mm), horizontally (front/back), and pivots ±15 degrees to match varying desk heights and shoulder widths.
Dynamic Lumbar Support System: Independent flexible lumbar panel self-adjusts based on user posture, applying consistent upward pressure to the L1–L5 vertebrae region.
Materials & Components
Mesh Upholstery: 70% elastomeric polyester and 30% nylon blend. Tensile strength exceeds 1200 N; passes 100,000 cycles Martindale abrasion test without fiber degradation.
Frame Construction: Injection-molded nylon with 30% glass fiber composite, offering high impact resistance and structural rigidity under continuous load.
Foam Cushion (Seat): High-density cold-cured polyurethane molded foam (density: 65 kg/m³), free from CFC emissions and engineered to prevent sagging over 5 years of commercial use.
Hardware: Grade 8.8 metric steel fasteners treated with anti-corrosion zinc plating.
